Consumers are being "bombarded" with financial jargon by banks and building societies, according to the director of retail at National Savings and Investments (NS&I).
While new research has found that jargon is driving customers away from banks and building societies, Julian Hynd said it was important for people to check the information supplied to them.
He said: "It's clear that customers are being bombarded with financial jargon, not only from their bank/building society but other financial service providers too."
He added: "But it's important for customers to remember that although the information supplied to them won't be a riveting read, it will provide essential information relevant to them."
